Non-slip self-tapping screw for container

Abstract

The utility model relates to an anti-thread-slipping self-tapping screw for a container, and aims to solve the problems that the self-locking purpose of the existing self-tapping screw is generally achieved only through friction between threads of the self-tapping screw and materials, but the container is easy to jolt in the transportation process, so that the self-tapping screw and a container body are easy to collide and abrade, and the service life of the container is influenced. The technical problems that in the prior art, due to the fact that a movable column is pressed downwards through an auxiliary mechanism, threads on the surface of a self-tapping screw are prone to being abraded, the self-tapping screw slips and moves out, and use of a container is affected are solved, and the self-tapping screw comprises a container body, and a plurality of self-tapping screw bodies are arranged on the surface of the container body. The movable column drives the movable rod and the movable block to move downwards, at the moment, the movable block extrudes the sliding block under the action of the inclined face, the sliding block is made to move horizontally, and therefore the end of the clamping rod can conveniently move out of the self-tapping screw body and be effectively connected with the connecting face of the container body in an embedded and clamped mode, and the fastening performance of the self-tapping screw body is improved. And the possibility that the self-tapping screw body slips and moves out is reduced.

[0002] Container transportation is an important mode of transportation in the process of multimodal transport of international trade goods. Due to the advantages of high standardization, good sealing, low breakage rate, intensiveness, scale, liner service, low cost and good quality, container transportation has greatly improved the safety and efficiency of cargo transportation. Self-tapping screws are required for the assembly of containers.

[0003] Existing self-tapping screws generally rely on the friction between their own threads and materials to achieve the purpose of self-locking. However, containers are prone to bumps during transportation, so collision and wear are likely to occur between the self-tapping screws and the box body, which can easily cause wear of the self-tapping screw surface threads, causing the self-tapping screws to slip and move out, affecting the use of the container. In view of this, we propose a container anti-slip thread self-tapping screw. Utility Model Content

[0025] The reinforcement mechanism 4 includes a movable column 401, a limit ring plate 402 is fixedly sleeved outside the movable column 401, and a group of springs 403 are arranged on both sides of the bottom of the limit ring plate 402, wherein the movable column 401 and the limit ring plate 402 are fixedly connected, and the limit ring plate 402 forms an elastic structure with the self-tapping screw body 2 through the spring 403, and a movable rod 404 is fixedly connected to the bottom of the movable column 401, and a movable block 405 is connected to the bottom of the movable rod 404, and a group of sliders 405 are symmetrically attached to the two sides of the movable block 405. 6. A clamping rod 407 is fixedly connected to the surface of the slider 406, a fixing rod 408 penetrates the inner side of the bottom of the slider 406, and a second spring 409 is sleeved on the outer side of the fixing rod 408. Further, both sides of the movable block 405 are respectively fitted with a group of inclined surfaces of the slider 406, and the slider 406 forms an elastic structure with the self-tapping screw body 2 through the second spring 409. A vertical rod 410 is connected to the bottom of the movable block 405. Further, a group of movable blocks 405 are provided, and a group of movable blocks 405 are connected through the vertical rod 410. The utility model presses the movable column 401 downward through the auxiliary mechanism 3, so that the movable column 401 drives the movable rod 404 and the movable block 405 to move downward. At this time, the movable block 405 is squeezed by the inclined surface to squeeze the slider 406, so that the slider 406 moves horizontally, thereby facilitating the end of the clamping rod 407 to move out of the self-tapping screw body 2 and effectively engage with the connecting surface of the container body 1, thereby improving the tightness of the self-tapping screw body 2 and reducing the possibility of the self-tapping screw body 2 slipping out.

[0026] It is worth noting that the auxiliary mechanism 3 includes an auxiliary pressure block 301, a group of limiting springs 302 are arranged on both sides of the auxiliary pressure block 301, a clamping block 303 is connected to the outer end of the limiting spring 302, and a pressing block 304 is attached to the end of the clamping block 303 away from the limiting spring 302, wherein the pressing block 304 is movably engaged with the inside of the screw head of the self-tapping screw body 2, and the pressing block 304 is in a cross shape. In the utility model, the clamping block 303 is first squeezed into the auxiliary pressure block 301, and then the auxiliary pressure block 301 is placed in the inside of the screw head of the self-tapping screw body 2. When the clamping block 303 is flush with the pressing block 304, the clamping block 303 pops out due to the rebound force of the limiting spring 302, and is effectively engaged with the inside of the screw head of the self-tapping screw body 2, so as to achieve the fixation of the auxiliary pressure block 301.
